APPARATUS FOR RAISING THE TEMPERATURE OF LIQUIDS.

Application filed March 8, 1919.

To all whom it may concern:

Be it known that 1, Oscar. Paint, a subject of the King of Great Britain, residing at Longue-Pointe, Province of Quebec, Canada, have invented certain new and useful Improvements in Apparatus for Raising the Temperature of Liquids; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to apparatuses for raising the temperature of liquids and more particularly to a heating unit to be used in connection with such apparatuses whereby the heating liquid will be retarded during its passage through the device so that the liquid to be heated will have ample time to assume the approximate temperature of the heating liquid, and the present invention is an improvement over my former Canadian Patent Number 173,338, dated May 29th, 1917.

An object of the present invention is to generally improve this class of apparatuses rendering them more durable, permitting a larger rotatingsurface within a small structure, and generally reducing the cost of manufacture of such apparatuses to render them more commercially desirable.

lVith the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown a simple and preferred form of the invention. it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which re course may be had that come within the scope of theclaims without departing from the spirit of the invention or sacrificing the efliciency of the same.

In the accompanying drawings:

Fig. 2 is a vertical transverse section through the same;

Specification of Letters Patent.

Patented Mar. 29, 1921.

Serial No. 281,509.

Fig. 3 is a detail side elevation of one of the heating units; and,

Fig. 4 is an end elevation of the same.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by similar reference characters throughout the several views.

The numeral 1 displays a cylindrical metallic casing which may be of any desired length, and the opposite ends of this casing are threaded so that the flanges 2 may be connected thereto. Connected to each of these flanges 2 by means of the bolts 3 are the plates 4, and arranged between the plates 4 and the flanges 2 is a suitable packing means 5. Formed within the periphery of the casing 1 and adjacent one end thereof is an inlet opening 6 and arranged adjacent the opposite end of the casing is an outlet 7 having greater interior diameter than the interior diameter of the inlet 6, whereby the liquid whose temperature is to be raised may flow freely within the casing 1, but when it exhausts from this casing may readily pass therefrom due to the enlarged diam: eter of the outlet. The plates 4 have threaded openings therein in which are adapted to be seated the plugs 8 and the purpose of these removable plugs is to permit anyone to inspect or see into the interior of the casing 1. Leading within the casing 1 and extending through the plate 4 arranged at one end of the casing is an inlet pipe 9, and extending through the other plate 4 is an outlet pipe 10. Arranged within the easing 1 is a plurality of heating units 11 and each of these heating units is cast in one piece of metal consisting of a cylindrical body portion whose outer periphery is corrugated as at 12 and the opposite ends of this body portion are closed by means of the corrugated end walls 13. Formed within each unit 11 is a partition 14 having a plurality of openings 15 arranged therein. The end walls 13 of each heating unit are provided with openings and encircling these openings are the internally threaded bosses 16. The nipples 17 connect the units together and are in threaded engagement with the bosses 16, but the threaded bosses arranged adjacent the opposite ends of the casing 1 are connected to the inlet and outlet pipes 9 and 10 respectively. Suitable supports 17 may be seated within the casing 1 so that the nipples 16 may rest thereupon, whereby the units may be further braced within the casing 1.

When the apparatus is in use the liquid whose temperature is to be raised may enter the casing 1 through the inlet 6 and circulate around the heating units 11. When the temperature of this liquid has been raised it will pass out through the outlet 7. The heating liquid which is preferably steam is admitted through the pipe 9 into the heating units 11 and finally it is permitted to exhaust through the pipe 10. The interior diameters of the pipes 9 and 10, as Well as the nipples 16, are so proportioned that the steam will be permitted to freely pass there through and to force with it any water deposited therein by condensation and the interior diameter of the inlet pipe 9 being the smallest the diameter of the successive nipples 16 will be gradually increased, and finally the interior diameter of the outlet pipe 10 is greater than the interior diameter of any of the nipples 16 or the inlet pipe 9. The partitions 14 will retard the steam as it enters each heating unit and the total area of the openings 15 within each heating unit is greater than that of the inlet pipe 9 or the nipples 16 leading to that particular unit, but the openings 15 are arranged out of direct line with the inlet leading to the unit. By this constructionit is obvious that when the heating liquid enters a unit it will be permitted to expand within the unit and will be slightly retarded before passing through the partitions 14 or entering into the adjacent nipple, and by having a plurality of these units within each casing 1 the steam will be retarded several times before exhausting through the outlet pipe 10. By so arranging the units within the casing 1 the liquid whose temperature is to be raised may be permitted to freely circulate around each unit, and by corrugating the outer peripheries of these units a larger rotating surface will be accomplished.

Due to the compact arrangement of this apparatus the same may be used for domestic purposes and the water or liquid whose temperature is to be raised may freely pass through the apparatus and its temperature will be raised in a comparatively short pe riod of time.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus of the character described the combination with a cylindrical casing, a plurality of units supported within said casing, nipples for connecting said units, an inlet leading to one of said units, an outlet leading from another of said units, supports for said nipples, and inlet and outlet pipes leading to said casing, said inlet and outlet pipes and said nipples having in.- creasing interior diameter, and the interior diameter of said outlet pipe being the greatest substantially as and for the purpose specified.

2. In an apparatus of the character described, the combination of a cylindrical casing, a plurality of units supported therein, nipples connecting said units, an inlet leading to one of said units, an outlet leading from another of the said units, supports within the casing and having seats receiving the nipples, perforated partitions extending transversely within the units, the said outer walls of the units being corrugated, said inlet and outlet pipes and nipples having increasing interior diameter and the interior diameter of the said outlet pipe being greater in diameter than the others, substantially as and for the purposes set forth.

In witness whereof I have hereunto set my hand.

OSCAR FARE.
